Q#1 GATE CH 2020 NAT +2 marks -0 marks

Liquid water is pumped at a volumetric flow rate of 0.02 m3 s−1 from Tank to Tank II, as shown in the figure.

             

Both the tanks are open to the atmosphere. The total frictional head loss for the pipe system is 1.0 m of water.

In addition, use the following data and assumptions

• Density of water of 1000 kg m−3

• Acceleration due to gravity is 9.81 ms−2

• Efficiency of the pump if 100 %

• The liquid surfaces in the tanks have negligible velocities

The power supplied (in W) by the pump to lift the water is _____ (round off to 1 decimal place).
